Understanding Cemented Tungsten Carbide: Defining & Evaluating Toughness

[@christopherleubner6633]

I have seen two types of these, one has a cobalt metal binder, the material is unbelievably hard but is not very tough. It breaks like glass. The other type has a nickel binder, it is much more tough but not as hard. The first is great for things like high speed circuit board drills or ball forming spheres, the second type is great where abuse is likely such as rock drills or saw teeth.
